RAILROAD-TRACK CONSTRUCTION.

Application led July 26, 1912.

To ZZ yrhome' m oy concern Be it known that l, JOHN lV. Lewis, a citizenof the United States, residing at Dexter, in the county of Cowley, Stateof Kansas, have invent-ed certain new and useful Improvements inRailroad-Track Construction; and l do hereby declare the following to bea full, clear, and eXact description of the invention, such as 'willenable other skilled in the art to'which it appertains to make and usethe same.

This invention relates to railroad track constructions.

The object of the invention resides in the provision of means forsupporting and fastening the rails of a railroad track without the useof wooden ties.

A further object of the invent-ion resides in the pro-vision of arailroad track construction which will eliminate the use of wooden tiesand at the same time permit the track to be laid and repaired withfacility.

vWith the above and other objects in view, the invention consists in thedetails of construction and in the arrangement and combination o-f partsto be hereinafter more fully described and particularly pointed out inthe appended claim.

1n describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the several views, and in which- Figure 1 is aplan view of a section of railroad track embodying the invention, Fig.2, a section on the line 2*-2 of Fig. 1, Fig. 3, a view similar to Fig.1 with the cross bars and rail clamping plates of the structure removed,and F ig. a, a detail perspective view of one of the side locking platesemployed in the structure.

Referring to the drawings the track illustrated is shown as constructedof parallel spaced metallic sills 10 and 11, the sills 10 Ybeingarranged on one side of the track in longitudinal alinement and thesills 11 correspondingly arranged on the other side of the track. Thesills 10 and 11 are curved in cross section, so that when placed uponthe ground they will be automatically locked against lateral movement.Each of the sills 10 and 11 has inserted therethrough, from the underside adjacent each corner, bolts 12 and seated upon the upper side ofthe sills 10 and 11 between transversely alined Specification of LettersPatent.

Serial No. 711,685.

bolts 12 are rails 13 and 11 respectively. Disposed upon the upper sideof each of the sills 10 and 11 are inner and o-uter side locking plates15 and 16, the inner side locking plate being engaged over the innermostlongitudinally alined bolts 12 and having its inner edge in engagementwith the inner edge of the base of the rail adjacent thereto, while theouter side locking plate is engaged over the outermost longitudinallyalined bolts 12 and has its inner edge in engagement with the outer edgeof the base of the adjacent rail. By this construction it will beapparent that the rails 13 and 14: are locked against movement laterallyupon respective sills l0 and 11. The rails 13 and 14 are secured againstvertical movement on respective sills 10 and 11 by means of inner andouter clamping plates 17 and 18 respectively. The inner clamping plates17 are engaged over the innermost longitudinally alined bolts 12 inoverlapping relation to the inner side locking'plate 15 and the base ofthe adjacent rail, while the outer clamping plate 18 is engaged over theoutermost longitudinally alined bolts 12 in overlapping relation to theouter side clamping plate 1G and the base of the adjacent rail. Afterthe outer clamping plate 18 has been applied to each sill same is forcedinto clamping relation to the base of the adjacent rail and the outerside locking plate 16 by means of nuts 19 engaged on the outermostlongitudinally alined bolts 12 respectively. Before the nuts 19 areapplied to the innermost longitudinally alined bolts of the sills 10 and11 cross bars 20 are engaged over the innermost bolts 12 atcorresponding ends of the sills 10 and 11 and in this manner the sillsare secured against spreading. After the cross bars have been thusengaged over the bolts 12 the nuts 19 are applied and operated to forcethe inner clamping plate against the inner side locking plate and thebases of adjacent rails. It will thus be seen that there has beenprovided a railroad track construction wherein the use of wooden ties isentirely eliminated and which at the same time will permit the track tobe laid with facility.

What is claimed, is

In a railroad track construction, a pair of parallel spaced sills, railsseated upon said sills longitudinally of the latter respectively, boltsprojected through each of said sills on each side of respective rails, apair of side lacking plates disposed upon each sill on opposite sidesoill the rail respectively and en gagged oi'er celtain of said bolts,the .inner edges of said side looking plates engaging the adjacent edgesof the rail base whereby said -fail is secured against movementlaterally, a. clamping plete disposed upon each side locking` plate andin overlapping Tela* tion to tlle adjacent Tail base, said clampingplete being engaged respectively oye-f ce1- tain olf seid bolts, elossplates having their ends engaged over corresponding bolts ot' yeepeetivesills and disposed upon the innermost clamping plates respectively, andnuts on seid bolts respectively for clamping the parts engaged by thevarious bolts together. ln testimony Wl1el'eof,lafllx my signetul'e, inpresence of two Witnesses.
